APCO ARV Clean Water Air Release Valves

Description

Air Release Valves have a small venting orifice and are used wherever air is entrained in water

under pressure. Their function is to release small pockets of air which gather at the high points

of a system after it is filled under pressure.

Handling and Storage

Lifting the valve improperly may damage it. Do not fasten lifting devices to ports in valve. Lift the

valve with slings, chains or cables fastened around the valve body, or fastened to bolts or rods

through bolt holes in the flanges.

If installation will be delayed, place valve indoors in secure, weather tight storage. If temporary

outside storage is unavoidable, make sure a vermin proof rain cover (water shedding tarp, etc.)

is secured around/over the valve to keep off rain and mud. Skid and set the assembly on a flat,

solid, and well drained surface for protection from ground moisture, runoff and pooled rain

water.

Installation

ARV Clean Water Air Release Valves should always be installed in a vertical position at high

points of a pipeline. An isolation valve between this unit and the transmission (pipeline) system

is recommended.

• Before installation, remove foreign material such as weld spatter, oil, grease, and dirt

from the pipeline.

• Prepare pipe ends and install valves in accordance with the pipe manufacture’s

instructions for the joint used.

Do not deflect the pipe-valve joint. Minimize bending stresses in the valve end

connection with pipe loading.

• Tighten the flange bolts or studs in a crisscross pattern and minimum of four stages.

• The ARV-50A valve is supplied standard with a 1” NPT female tap on body. If a ¾” or

½” NPT female connection is desired, a reducer bushing should be used. Included in the

box is a 1” NPT male to ¾” NPT female and 1” NPT male to ½” NPT female hex reducer

bushing. Install the male 1” NPT thread into the body as shown in Figure 1 using a

thread sealant.

Fusion/Powder Coated Valves

Valves with fusion/powder coated exterior paint require flat washers to be

installed under the flange nuts when installing the valve to the pipeline

flange to prevent the paint from cracking or chipping.

Maintenance

Air Release Valves are automatic in operation and require very little or no maintenance.

It is recommended that they be checked visually semi-annually for leakage. A malfunction of

the valve will be evident by leakage of the media through the small orifice. Should a malfunction

occur, the following steps should be taken to repair the valve.

Cleaning of Seat Orifice

See Figures 1 thru 8 for part identification.

Servicing the Air Valve while the pipeline is under pressure can cause personal

injury or equipment damage. Relieve pipeline pressure or shut off isolation valve

before servicing the Air Valve.

1. Relieve pipeline pressure or shut off isolation valve at inlet to Air Release Valve.

Do not completely remove pipe plug or cover screws while the valve is under

pressure.

2. For ARV-55, ARV-65, ARV-200A ARV-200, ARV-205, ARV-206 and ARV 207 loosen

pipe plug on body (R1) or cover (R2) to relieve internal pressure. Do not completely

remove pipe plug while the valve is under pressure.

For ARV-50A Valves: Loosen the cover bolts (R4) to allow internal pressure to escape.

Once pressure is completely released, re-tighten cover screws. Do not completely

remove cover screws while the valve is under pressure.

3. Remove pipe plug. (Except ARV-50A)

4. Connect air or preferably water to orifice outlet and blow down into valve to clean any

sediment that may be clogging orifice.

5. Disconnect air or water connection from orifice outlet.

6. Replace and tighten pipe plug. (Except ARV-50A)

7. Open isolation valve on inlet to Air Release Valve. Valve is now back in service. If this

procedure has not remedied the problem, proceed with disassembly.

Disassembly Procedure

See Figures 1 thru 8 for part identification.

Servicing the Air Valve while the pipeline is under pressure can cause personal injury

or equipment damage. Relieve pipeline pressure or shut off isolation valve before

servicing the Air Valve.

1. Relieve pipeline pressure or shut off isolation valve at inlet to Air Release Valve.

Maintenance (Continued)

Do not completely remove pipe plug or cover screws while the valve is under

pressure.

2. Loosen cover bolts (R4) to allow internal pressure to escape.

3. Remove cover bolts (R4) and cover (R2). All internals are attached to cover except

ARV-55 and 65.

4. For ARV-55 and 65 valves: Unscrew side plug (R32) to remove float (R14) and needle

(R7). To remove seat (R6), unscrew it from orifice outlet with a flat bar 1/8” t X 1/2” w.

5. If cover gasket (R3) is torn or damaged, it must be replaced. Clean flange surfaces of

cover (R2) and body (R1).

6. Inspect sealing surface of needle (R7) and seat (R6) for nicks, wear or sediment coating

from chemicals in the media.

7. Clean or replace needle (R7) and seat (R6).

8. Inspect float (A14) to insure that it is not damaged or that it does not have liquid in it.

9. Inspect all connections of linkage for excessive wear.

10. Clean all surfaces before re-assembly.

Assembly Procedure

See Figures 1 thru 8 for part identification.

1. Re-assemble in the opposite order as disassembly procedure.

2. Assemble cover (R2) to body (R1), installing new gasket (R3) if necessary. Tighten

cover bolts (R4) opposite each other in rotation.

3. Open isolation valve on inlet to Air Release Valve. Valve is now back in service.

Operation

The Air Release Valve is automatic in operation. They have much smaller orifices than

Air/Vacuum Valves. They release small pockets of air that gather at the high points of a system

after it is filled and under pressure. The Air Release Valve has the ability to open against

internal pressure because it has a small orifice and a leverage mechanism that multiplies the

force of the float. This force must be greater than the internal pressure across the orifice in

order to open the orifice when a pocket of air needs to be vented.
